Change default screenshot format

Mac screenshots by default save in .png format. Would you prefer the default format to be JPG, or something else? Here's the simple way to change it.

From Finder, launch Terminal:

top menu  Go > Utilities > Terminal

Copy and past in the following line, it's a single line with no break:

defaults write com.apple.screencapture type jpg;killall SystemUIServer

Want a different format? In this line of code, replace jpg with one of the following:

gif

PDF

png

tiff
